Overview of the LabVIEW Robotics Module
The Robotics Module extends the LabVIEW graphical development environment with additional
functionality for robotics development, control, and application. The LabVIEW Robotics platform
provides a standard hardware and software development solution for designing your robotic control
system. The Robotics Module plugs into the LabVIEW development environment and delivers an
extensive robotics library with built-in connectivity to robotic sensors and actuator, foundational

algorithms for intelligent operation and robust perception, and motion functions to make the robot or
vehicle move.
The Robotics Module includes all the necessary software tools to design a sophisticated autonomous or
semi-autonomous system. The Robotics Module also provides VIs and example programs for designing
algorithms and applications that you can deploy to a robotics system. With the Robotics Module, you
can communicate with sensors and actuators, design and control serial robotic arms, create robotics
applications, and simulate robots in a simulation scene you create.
The Robotics Module also adds components, such as VIs and device drivers, setup wizards, simulator,
and examples, to the LabVIEW Development System. Refer to the LabVIEW Help for more information
about the components that the Robotics Module adds to LabVIEW and about using these components
in the LabVIEW Robotics environment.
With the Robotics Module, you can create a robotics project. Refer to the Creating a Robotics Project
section of this manual for information about creating a Starter Kit project using the Robotics Project
Wizard. You also can create a simulation project using the Robotics Environment Simulator Wizard.
Choose Robotics Environment Simulator on the Select project type page of the Robotics Project
Wizard to launch the Robotics Environment Simulator Wizard. Refer to the LabVIEW Help for
detailed information about designing a simulated environment and simulated robots.
Accessing LabVIEW Robotics Software
The Robotics Module provides a different environment than the LabVIEW Development System to
allow you to easily access robotics-specic features and focus on developing robotics applications. To
access the LabVIEW Robotics environment, select Start»All Programs»NI LabVIEW Robotics x,
where xis the LabVIEW version.
If LabVIEW is already open, select Tools»Choose Environment to display the Choose Environment
Settings dialog box, which you can use to change environments.
In the LabVIEW Robotics environment, you can access Robotics specic tutorials and the Hardware
Setup Wizard by clicking the Welcome link on the Robotics Getting Started window.
Components of a LabVIEW Robotics System
A robotics system consists of software and hardware components. In a system designed with the LabVIEW
Robotics Module, the software components include National Instruments software, such as the projects
and VIs you create in LabVIEW. The hardware components of a robotics system might include the
following:
•Host computer—Develop and debug robotics applications on a host computer. You also can
communicate with the robot and log data it acquires using the host computer. Run applications you
develop on the host computer, or deploy them to a Windows-based system or real-time controller.
•Robot control system—Construct a robot steering frame that includes the following components:
–Real-time controller—Deterministically run the programs you create in LabVIEW and control
data input and output with a real-time, or RT, controller, which serves as the “brain” of the
system.
–Sensors and actuators—Acquire data about the robot environment with sensors, such as laser
range nders, and control robot motion with actuators.
The LabVIEW Robotics Starter Kit is an example of a robotics system that consists of these components
and runs LabVIEW and Robotics Module software. On the Starter Kit robot, a Single-Board RIO
controller, mounted on top of the robot base, includes a real-time processor and Field-Programmable
Gate Array (FPGA) on a single board. By default, the FPGA has a sensor and motors wired to digital

I/O: an ultrasonic distance sensor, a servo motor on which the sensor is mounted, and two DC drive
motors. Figure 1 shows the components of a LabVIEW Robotics Starter Kit robot.

Note Refer to the Robotics Module»LabVIEW Robotics Starter Kit book on the Contents
tab of the LabVIEW Help for more information about the Robotics Starter Kit.
The remainder of this manual uses the Robotics Starter Kit as an example to explain the process of
getting started with a typical robotics system and the Robotics Module.
Host Computer
The host computer is a computer with the LabVIEW Development System and LabVIEW modules and
toolkits installed on which you develop the VIs for the robotics system. After you develop the robotics
VIs, you can download and run the VIs on RT and FPGA targets, such as CompactRIO and Single-Board
RIO products. The host computer also can run VIs that communicate with the VIs running on targets to
provide a user interface.
LabVIEW Projects
Use LabVIEW projects on the host computer (1) to group LabVIEW les and les not specic to
LabVIEW, create stand-alone applications, and deploy or download VIs (3) and applications to RT (2)
and FPGA targets that contain I/O modules (4). When you save a project, LabVIEW creates a project
le (.lvproj), which can include references to les in the project, conguration information, build
information, and deployment information. Figure 2 shows the parts of a typical LabVIEW project.

Figure 2. Parts of a LabVIEW Project
From the Getting Started window, click the Create Project button and follow the instructions to create
a new LabVIEW project. You also can use the Robotics Project Wizard to create a LabVIEW project
from a template. Refer to the Creating a Starter Kit Project Using the Robotics Project Wizard section
of this manual for information about creating a LabVIEW robotics project using the Robotics Project
Wizard.
Real-Time Controller
Real-time controllers run programs you create in LabVIEW. On the Starter Kit robot, the Single-Board
RIO is the real-time controller. Some real-time controllers, such as NI Single-Board RIO products,
consist of a real-time processor and operating system and a Field Programmable Gate Array (FPGA).
Other NI real-time controllers, such as PXI products, contain only a real-time processor. You also can
use certain third-party hardware, such as ARM microcontrollers, to run LabVIEW programs. Use the
Getting Started with the LabVIEW Robotics Module 4ni.com

Project Explorer window to congure third-party hardware similarly to how you congure an NI RT
or FPGA target.
Real-Time Target
The real-time processor and operating system, or RT target, serves as the “brain” of the robotics system,
running VIs you create using LabVIEW. Robotics applications require many tasks to complete
deterministically, or within a guaranteed time period. The RT Engine, a version of LabVIEW that runs
on RT targets, deterministically executes VIs in which you prioritize tasks so that the most critical task
can take control of the processor when necessary.
FPGA Target
An FPGA is an embedded chip that you can congure to match the requirements of a specic system.
Some controllers, such as CompactRIO and Single-Board RIO products, contain integrated FPGA targets,
which are directly connected to the I/O modules that access sensor and actuator data. FPGAs automatically
communicate with I/O modules and provides deterministic I/O to the real-time processor. Thus, you
typically program the FPGA to perform the lowest-level I/O and control tasks with the most critical
level of timing in a robotics application.
On the Starter Kit robot, you might want to program the FPGA to read obstacle data from the distance
sensor and adjust the drive motors accordingly to run deterministically so the robot avoids obstacles.
You can use LabVIEW programming techniques to develop an FPGA VI on the host computer and
download the VI on the target.
I/O Modules
National Instruments offers a variety of I/O modules that directly connect to sensors and actuators. On
the Starter Kit robot, built-in I/O connects the FPGA to the sensor and actuators. You typically write an
FPGA VI to access I/O, and then use an RT VI to read from and write to the I/O in the FPGA VI.
Sensors and Actuators
Robotics systems acquire data about the environment around them with sensors, such as laser range
nders, and move through the use of actuators. On the Starter Kit robot, the distance sensor detects
obstacles in the path of the robot, a servo pans the sensor back and forth, and drive motors propel the
robot.
Use sensor and actuator drivers from the Robotics palette in an RT or FPGA VI to communicate with
sensors and actuators like the ones on the Starter Kit robot. Drivers reduce program development time
by eliminating the need to learn the programming protocol for each device. Refer to the Where to Go
from Here section of this manual for information about nding sensor drivers.
Configuring Software and Hardware for a Robotics System
The remainder of this manual contains exercises to teach you how to build and deploy a robotics
application for the Starter Kit robot, a typical RIO-based LabVIEW robotics system. You can extend
the information in this exercise to other, similar robotics systems.
Before you create a LabVIEW project and application to deploy to a hardware target, you must install
software on the host computer and congure the target on which you want the application to run.
Installing Software and Device Drivers on the Host Computer
Refer to the readme le on the Robotics installation media for information about the National Instrument
products to which you have access, system requirements, and instructions for installing LabVIEW,
modules, and toolkits on the host computer.
©National Instruments 5Getting Started with the LabVIEW Robotics Module

Configuring an RT Target
Before you can deploy robotics applications to an RT target, you must congure the basic settings of
the target and install software on the target. To congure the Single-Board RIO on the Starter Kit robot,
use the National Instruments Robotics Hardware Setup Wizard, which launches after you install the
LabVIEW Robotics software on the host computer. You also can click the Welcome link on the Getting
Started window and click the Hardware Setup Wizard link to launch this wizard manually.
If you use a CompactRIO or non-Starter Kit Single-Board RIO, you also can use this wizard. However,
if you use any other type of target, use the National Instruments Measurement & Automation Explorer
(MAX) to detect, congure, and test an RT target. MAX provides access to National Instruments devices
and systems, so you can use MAX to communicate with networked RT targets located on the same
subnet as the host computer. Select Start»All Programs»National Instruments»Measurement &
Automation Explorer to launch MAX and refer to the MAX help for more information about conguring
targets in MAX.
In the Robotics Hardware Setup Wizard, complete the instructions that appear on the screen to perform
the following tasks:
• Set the IP address of the target you want to use
• Download software to the target that can run VIs you deploy to the target
• Test that the target is congured correctly
The host computer communicates with the remote system over a standard Ethernet connection. If the
host computer is already congured on a network, you must congure the remote target on the same
network. If neither machine is connected to a network, you must connect the two machines directly using
a CAT-5 crossover cable or hub.
On the nal page in the Robotics Hardware Setup Wizard, exit the wizard and launch LabVIEW to
continue this exercise. When LabVIEW launches, the Robotics Project Wizard displays.
Tip If you do not have the Robotics Starter Kit, you can launch LabVIEW and click the Create
Project button on the Getting Started window and select the Robotics Project template from
the Create Project dialog box to launch the Robotics Project Wizard.
Creating a Robotics Project
With the Robotics Module, you must use a LabVIEW project (.lvproj) to build and congure robotics
applications and to work with RT and FPGA targets. Use projects to group LabVIEW les and
non-LabVIEW les, congure communication between hardware, create build specications, and deploy
les to targets.
Refer to the topics in the Fundamentals»Working with Projects and Targets book on the Contents
tab of the LabVIEW Help for more information about LabVIEW projects.
For this exercise you will use the Robotics Project Wizard to create an application that drives the Starter
Kit robot. The application consists of a VI that acquires data from the distance sensor, calculates a
heading for travel, and then applies the correct amount of velocity to the drive motors.
Note You can complete some of the same the steps in this exercise even if you do not have
the Starter Kit. The process this exercise describes is similar to the process for creating an
application for a non-Starter Kit RT target or a Windows-based target.

9. Click Finish to exit the Robotics Project Wizard and generate the new project, VIs, and support
les for the robotics application. The Project Explorer window displays the new project that you
create.
Exploring the Project in the Project Explorer Window
The Project Explorer window enables you to manage hardware targets, VIs, and other support les
from one location. In the project you create, the Project Explorer window includes the following
sections:
•Project root—Contains the host computer, the Starter Kit RT target and I/O, and VIs that control
the target.
–My Computer—Represents the host computer in the project.
•Dependencies—Includes items that VIs under the host require.
•Build Specications—Includes build congurations for source distributions and other
types of builds. You can use Build Specications to congure stand-alone applications,
such as one that launches automatically when you power on the target.
•Simulated Starter Kit 2.0 Roaming—Organizes the les that dene and control
components in a particular simulation scene.
–Simulated Starter Kit 2.0 Roaming.xml—Serves as the manifest le that contains
denitions for components in the simulation scene you create. LabVIEW adds this
item to a project when you use the Robotics Environment Simulator Wizard to
create a simulation scene.
–Simulated Starter Kit 2.0 Roaming.vi—Starts and stops the simulator, serves as
a user interface for the simulation, and calls LabVIEW code that manipulates
components in the simulation.
–Simulated Starter Kit 2.0 Roaming ID List.txt—Contains the ID names of the
components in the simulation scene you create. LabVIEW adds this item to a project
when you use the Robotics Environment Simulator Wizard to create a simulation
scene.
–Starter Kit 2.0 sbRIO—Represents the real-time controller on the Starter Kit robot and
contains the I/O through which you access sensors and actuators. The Project Explorer
window also includes Dependencies and Build Specications sections under this target.
VIs and libraries that you add to a hardware target appear under the target to indicate that you can run
the VI on that target. Figure 4 shows a project similar to the Robotics Project.lvproj le you
created with the Robotics Project Wizard.

Figure 5. Block Diagram of the Test Ultrasonic Sensor VI
On the previous block diagram, the following VIs from the Starter Kit palette allow you to communicate
with the sensor and actuators connected to I/O on the Starter Kit robot. Although this VI is fairly simple,
the block diagram illustrates a common workow for controlling RIO-based mobile robots.
• The Initialize Starter Kit 2.0 (sbRIO-9632) VI begins a communication session with the FPGA on
the robot and returns a reference you use to read from or write to the FPGA.
• The Write Sensor Servo Angle VI writes an angle to the servo on which the distance sensor is
mounted to turn the servo to that angle.
•The Read PING))) Sensor Distance VI reads and returns the distance between the ultrasonic distance
sensor and the nearest obstacle the sensor detects.
• The Close Starter Kit VI terminates the communication session with the FPGA on the Starter Kit
robot.
Tip Select Help»Show Context Help to display the Context Help window, which displays
basic information about LabVIEW objects and the LabVIEW environment when you move the
cursor over each object.
These VIs and others from the Starter Kit palette allow you to control the Starter Kit FPGA from an RT
VI without writing an FPGA VI. To control a non-Starter Kit robot whose real-time controller contains
an FPGA target, you typically must write an FPGA VI that runs on the real-time controller and accesses
I/O. Figure 6 shows the block diagram for a simple RT VI that communicates with an FPGA VI to
perform the same task as the Test Ultrasonic Sensor VI.

acquires obstacle data from the distance sensor, calculates the heading to which the vehicle drives,
and applies the correct velocity to the drive motors.
6. Close the Starter Kit 2.0 Roaming VI and return to the project.
Configuring Target Properties
Use the Properties dialog box to congure the project settings of the Single-Board RIO target from the
Project Explorer window. You can congure general, VI Server, access, debugging, and miscellaneous
target settings, depending on the target you are conguring.
Right-click the Starter Kit 2.0 sbRIO target in the Project Explorer window and select Properties
from the shortcut menu to open the target Properties dialog box and select an item from the Category
list to display the conguration options. Select Project»Save Project from the Project Explorer window
to save the project and settings you selected for the target in the target Properties dialog box.
You must deploy the target before the settings take effect. Deploying a target refers to applying settings
dened in the project to a target.
Note Deploying a target overwrites the current target settings with the latest settings specied
in the target Properties dialog box.

Overview of Robotics Application Architectures
The Starter Kit 2.0 Roaming VI serves as an example of a robot that performs simple, repetitive
algorithms. You can insert code for acquiring sensor data, processing data, and controlling the robot
inside the Timed Loop.
An advanced robot architecture also might include Timed Loops that detect obstacles, control movement,
and measure the progress of the robot. Loops can run on different hardware targets, so you must implement
communication between processes on different targets as well as between different processes that run
on the same target.
Refer to the Robotics Module»Communicating between Processes in a Robotics Application book
on the Contents tab of the LabVIEW Help for more information about sending data between VIs.
Note Select Help»Find Examples in LabVIEW to launch the NI Example Finder, where
you can nd specic example architectures. The Robotics category opens automatically.
Deploying and Downloading VIs to a Target
Before you run VIs on an RT or FPGA target, you must deploy RT VIs and any dependencies to the RT
target and download les on the FPGA target.
Deploying VIs to RT Targets
When you run an RT VI under an RT target, LabVIEW deploys RT VIs, all items required by the VIs,
and the target settings to the target. You can deploy VIs, libraries, and shared variables to an RT target
where you can run or reference the items.
Complete the following steps to deploy and run the robotics application you created with the Robotics
Project Wizard.
1. Right-click the Starter Kit 2.0 Roaming.vi under the RT target in the Project Explorer
window and select Deploy from the shortcut menu to download the VI to the RT target.
LabVIEW deploys the VI to the RT target and opens the front panel to indicate that the VI is in
memory on the RT target. Closing the front panel removes the VI from memory on the RT target.
2. Click the Run button to run the VI on the target.
3. Click the Stop button to stop the execution of the Timed Loop in the RT VI, which stops the
execution of the VI.
Note Deploying an RT VI does not save the VI to disk on the RT target, so the VI does not
remain on the target after the target restarts. Refer to the Building a Robotics Application that
Runs at Startup section for information about building and running a stand-alone application
that remains on the RT target and runs when the target powers on.
Downloading VIs on FPGA Targets
The project you created with the Robotics Project Wizard does not contain FPGA VIs. However, when
a project does contain an FPGA VI, you must compile the VI before you can download and run the VI
on an FPGA target.
Refer to the Robotics Module»Creating Robotics Applications»Deploying, Downloading, and
Running VIs and Applications topic on the Contents tab of the LabVIEW Help to access information
about compiling, downloading, and running FPGA VIs.
©National Instruments 13 Getting Started with the LabVIEW Robotics Module

Building a Robotics Application that Runs at Startup
Use the LabVIEW Application Builder with the Real-Time Module to create a stand-alone robotics
application that runs on an RT target. Stand-alone applications do not require you to run them from
within a LabVIEW environment. You can embed a stand-alone application on an RT target and congure
the application to launch automatically when you power on the target. Use the Application Builder to
create a build specication that denes how you want to build an application.
Creating a Build Specification
A build specication denes the VIs, support les, and settings for a stand-alone application. You must
create a build specication and then use the build specication to build the application.
Complete the following steps to create a build specication from the project you previously created.
1. Right-click Build Specications under the RT target in the Project Explorer window and select
New»Real-Time Application from the shortcut menu to open the Real-Time Application
Properties dialog box.
2. Enter Robotics Application in the Build specication name text box. The build specication
name appears under Build Specications for the RT target.
3. Enter roboapp.rtexe in the Target lename text box to set the le name for the application
executable on the RT target. By default, the Target lename text box contains startup.rtexe.
4. Click Source Files from the Category list to display the Source Files page.
5. From the Project Files tree, select the Starter Kit 2.0 Roaming.vi, located under the RT
target, and click the right arrow button to move the VI into the Startup VIs list, as shown in Figure 9.
VIs in the Startup VIs list execute when you launch the application.
Getting Started with the LabVIEW Robotics Module 14 ni.com

Figure 9. Selecting a Startup VI
6. Click the OK button to accept the settings and close the Real-Time Application Properties dialog
box. The build specication name appears in the Project Explorer window under Build
Specications for the RT target.
7. Select Project»Save Project from the Project Explorer window to save the project and the build
specication settings.
Building and Running a Startup Application
After you create a build specication, you can build and run an application on an RT target. You also
can set the application to launch when you power on the RT target.
Complete the following steps to build and run an application on an RT target.
1. Right-click the Robotics Application build specication and select Build from the shortcut menu
to build the application. The Application Builder builds the application using with the settings you
dened in the build specication. When the build completes, click the Done button to close the
Build Status dialog box.
2. Right-click the build specication and select Run as startup from the shortcut menu. The Run as
startup shortcut menu item sets the application as the startup application, deploys the application
to the target, and prompts you to restart the RT target. When you set a build specication as the
startup application, LabVIEW displays the build specication with a green border around the
specication icon in the Project Explorer window.

3. After you restart the RT target, the application generated from the build specication launches
automatically and begins running the simulated navigation program.
Note If you plan to continue editing the RT VI, you might not want the application to
run every time you power on the RT target. To uncongure the application as startup,
right-click the build specication and select Unset as startup and then Deploy from the
shortcut menu.
